Proper use of apostrophe?

[Olympian]

Hello,

Please tell me if the following use of apostrophe is correct or not.

Williams' ouster eventually led to the resignation of NPR chief Vivian Schiller's, and a black eye for its image.

Is it correct to say 'resignation of NPR chief Vivian Schiller'? Or is the apostrophe needed here?

Thank you

Your correction is right. The apostrophe s is a mistake.

I expect I'm the only one who didn't know that ouster meant dismissal until I looked it up.

Williams' is the form used by some people, but most prefer the clearer Williams's. Schiller's is wrong, It should be Vivian Schiller's resignation or the resignation of Vivian Schiller.

@Rover, thank you. I wonder if 'ouster' as 'dismissal' is more AmE

@fivejedjon, thank you. Also, thanks for clarifying about Williams'/Williams's

@Rover, thank you. I wonder if 'ouster' as 'dismissal' is more AmE It might be. Though it is formal, I hear it on a regular basis.

"Ouster" is a common expression for the dismissal of a person (usually a public figure) in AmE.
